SPECIFICATION forming part of Letters Patent No. 265,613, dated October 10, 1882.

Application tiled May 17, 1882. (No model.)

To all whom it 'may concern:

Be it known that l, FREDERICK J. KALDEN- BERG, a citizen of the United States, residing at New York, in the county and State of New York, have invented a certain new and useful Improvementin Mouth-PiecesorBitsforPipes, &c., ot' which the following is a specitication.

My invention relates to improvements in mouth-pieces or bits for attachment to pipes or for use with cigars, and the improvement is more especially designed for mouth -pieces which are molded or otherwise formed out of a composite material consisting ot' several ingredients united together, such as celluloid, coralline, lignoid, Src.; and the object ot' my invention is to so construct the mouth-piece that the material ot' which it is composed will be preserved against the direct action of the heat and heated smoke that is drawn through it, and also to aiit'ord greater' facility in mounting. s

Heretoi'ore this class ot niouthpieces or pipebits-that is, those made from plastic materials, such as rubber, celluioid, lignoid, Xylonite, Ste-have been provided with a threaded end for screwinginto the pipe-band. 'lhe cutting ot' the screw outot' the materialritselt' has been found very objectionable for several reasons, thc most important ot' which are that the action ot' the saliva on the material soon causes the screw end to rot or decompose, thereby destroying and breaking ofi' its thread and rendering the fastening useless; Again, where the mouth-piece and stem-band to which it is secured arc made ot' an oval shape, as seen in Fig. 3, and the screw is cut upon the mouthpiece, it is a very difficult matter to cut the thread on the mouth-piece with corresponding accuracy to the internal thread on the steinbaud, and considerable labor is often required to adjust the mouth-piece, ai'ter being screwed in, so as to make a tight joint and also bring the two oval edges into uniformity with each other.

The purpose of my invention is to overcome these diiculties; and to attain this end I make the mouth-piece with asmooth bore, (or without the usual screw-thread in the smoke-aperture for screwing it to the pipe-sten1,)and into this' aperture I insert a tube having' a plain suri'ace formed ot' metal or other suitable impermeable material, the said tube projecting beyond the aperture and having its projecting end screw-threaded externally to screw into the high band or stem ot' the pipe. By forming` the screw on the end ot' a tube, as stated. I am enabled to dispense with the cutting ot' the screw on the material of which the mouthpiece is composed.

In the accompanying drawings, which serve to illustrate myimprovement,Figure lis a side view ot' a pipe having my improved mouthpiece attached thereto, the stemband and mouth piece being shown in section. Fig. 2 is a longitudinal section of the mouth-piece removed; and Fig. 3 is a cross-section of the mouth-piece, taken on line g/ y, Fig. 1.

Referring to Fig. l, d is the pipe; b, the high band of metal which lits over the stem ot' the pipe, and which is provided with an internal screw-thread on its upper end, andc the mouthpiece, which is screwed into the band b. Instead ot forming the screw on the mouth-piece for engagement with the stem-band, as has always been done where, they are made from plastic compounds, I provide a tube, d, which is castor otherwise formed out ot' block-tin, spelter, orother suitable metal, having` a screwthread on one ot' its ends, which is inserted through the bore or perforation c in the mouthpiece c. This tube extends to the top of the mouth-pieceand serves to protect thc inner surface ot' the mouth-piece from the direct action ot'the heatand smoke, which have adestructive eit'ect upon the compound, causing a partial decomposition. As this decomposition takes placedisagreeableodors and vaporsare thrown oft', which mingle with the smoke and are drawn into the smokers mouth, producing an unpleasant taste. This objection islikewise overcome by the use ot' my improvement. Before inserting the metal tube into the mouth-piece it is dipped in a solution made by dissolving bits ot' the material or compound out of which the mouth-piece is made in wood-alcohol until the surface to be inclosed is quite covered,

when it is driven in the mouth-piece down to,

the screw' endj'. in a short time the tube will become rml'y embedded in the mouth-piece. The screw end f oi' the tube is then screwed into the stem-band I).

In mountingthe oval mouth-pieces the tube IOO dis preferably first screwed into the stem-band, and the mouth-piece then forced down onto it. Heretofore it has been impossible to make a perfect joint where the mouth-piece and band connect, in the longl oval form, without convsiderable labor, as sometimes the thread is so that it' it screws in tightly the ovals are not uniform, and vice Versa, so that often there is much labor in getting a tight joint and still preserving the uniformity of the ovals at the same time. By using the Aindependent screw as formed on the tube this difficulty is entirely overcome, and the oval forms are as easily mounted as the round ones. Where the screw is formed ou the mouth-piece it soon becomes useless, owing to the action of the heat and saliva on its exposed surface, and the monthpece is then of no vaille. By my improvement this is obviated,and a mouth-piece made ot' the plastic compounds is rendered more durable andas pleasant to use as those made out of pure amber. The tube may be made of any other suitable material than metal, if desired.

What I claim as new, and desire to secure by Letters Patent, is

1. As a new article of manufacture, a mouthpiece for pipes, having a. tube arranged within the smoke-aperture and which projects beyond the lower end thereof, the inelosed portion of said tube having a smooth surface, and the projecting end provided with ascrew-thread, substantially as and for the purpose set forth.

2. Amouth-piecehavingatubeofimperineable material cemented Within the smoke-aperture and projecting' therefrom, the projectiu;r end only of said tube heilig screw-threzuled, as and for the purpose set forth.

3. The combination, with the band b and mouth'piece c, of the tube d, provided with the screwf, Substantially as and for the purpose set forth.
